Cimetidine is approved by the U.S. Food and Drug Administration (FDA) and is safe and effective when used according to label directions. Cimetidine may interact with certain prescription drugs. If you are taking a prescription asthma medicine, seizure medicine, or blood thinner, speak with a healthcare professional before using an OTC medicine containing cimetidine.

You take too much. Immediately contact a doctor or the poison control national helpline at 800.222.1222.

If you have questions about any of the medicines you are taking or if you have any unexpected side effects, talk to a healthcare professional. And of course, keep all medicines out of the reach and sight of children.
